Zorluk: ZorReduction of Risk Potential

A licensed practical nurse (LPN) is preparing to collect an aerobic wound culture from a client's purulent abdominal surgical incision. In what order should the LPN perform the following steps to ensure an accurate specimen? Arrange the actions in the correct chronological sequence.

  1. 1Remove the soiled dressing and assess the appearance of the wound bed.
  2. 2Cleanse the wound bed with sterile normal saline.
  3. 3Rotate a sterile culture swab over an area of clean granulation tissue.
  4. 4Place the swab securely into the sterile culture tube.
  5. 5Apply a new sterile dressing over the abdominal incision.

Cevap

The correct sequence is to remove the soiled dressing, cleanse the wound with sterile normal saline, rotate the swab over clean granulation tissue, place the swab into the culture tube, and apply a new sterile dressing.
To collect an accurate wound culture that directs appropriate antibiotic therapy, the nurse must first remove the old dressing. Crucially, the wound must then be cleansed with sterile normal saline. Culturing uncleansed purulent drainage often yields resident skin flora or dead organisms, leading to inaccurate results. After cleansing, a sterile swab is rotated over clean, viable granulation tissue. The swab is then immediately placed into the sterile transport tube to prevent contamination, and finally, a new sterile dressing is applied to protect the wound.

Adım Adım Çözüm

1
Remove the soiled dressing and assess the appearance of the wound bed.
The wound is exposed and ready for evaluation.
The old dressing must be removed to access the site and determine where the culture should be taken.
2
Cleanse the wound bed with sterile normal saline.
Surface exudate, pus, and resident skin flora are washed away.
Culturing uncleansed surface pus yields inaccurate results; the goal is to identify the pathogen actively invading the tissue, not surface colonizers.
3
Rotate a sterile culture swab over an area of clean granulation tissue.
The pathogen causing the deep infection is collected.
Actively growing pathogens are concentrated in viable granulation tissue, providing the most accurate diagnostic specimen.
4
Place the swab securely into the sterile culture tube.
The specimen is secured in its transport medium.
Immediate placement prevents environmental contamination of the swab and protects the nurse from exposure.
5
Apply a new sterile dressing over the abdominal incision.
The wound is protected from the external environment.
Restoring the protective barrier is the final step after the procedure is complete.

Anahtar Kavram

Accurate wound culture collection requires cleansing the wound with sterile saline prior to swabbing to avoid capturing surface colonizers or old exudate.
